[APM] Pulls legacy ML code from service maps and integrations (elasti…

…c#69779)

* Pulls out existing ML integration from the service maps

* - removes ML job creation flyout in integrations menu on the service details UI
- removes ML searches and transforms in the transaction charts API
- removes unused shared functions and types related to the legacy ML integration

* removes unused translations for APM anomaly detection

* Adds tags to TODOs for easy searching later
